To all whom it may concern/. v

' Be it known that I, WlLLrAMlNlLsoiv, a citizen of the United States,residingat Boston, in thecounty of Sufiolk and State of Massachusetts,have invented certain new and useful Improvements in Work-GuidingDevices; and I do hereby declare the follow-. ing to 'be a full, clear,and exact description of the invention, such as will enable othersskilled inthe art to which it appertains'to make and use the same.

This invention relates to improvements in work-guiding attachments forsewing-machines.

In the o eration of sewing-machines which are a apted for erforming workof various characters suc l, for instance,- as WaX- thread sewinmachines which are adapted for sewing harness, hand-bags, andvarious'kinds of leather oodsit is neces-, sary inv adapting such macines to the different characters of work performed to use variouswork-guiding devices or attachments for uiding the materials operatedupon.

T 1e present invention relates to improvements in the construction ofsuch attachments; and one object of the invention is to produce meansfor mounting and securingguiding devices upon a sewing-machine whichwill permit the convenient adjustment of such devices and which may beused in 1 connection witha variety of different devices.

Another object is to produce an improved edge-gage attachment forsewing-mach nes. The invention consists in the work-guidmg attachmenthereinafter described as defined in the claim.

In the drawings, Figure 1 is a side eleva tion of a work-guidingattachment embod ing the present invention, together with tlie adjacentparts of a sewing-machine in connection vwith which it is used. Fig. 2is a plan view of the attachment. 4 front elevation of the upper portionof the attachmehtwith the edgeage removed. Fig. 4 is a vertical sectionof t p e same part. Fig.

7 5 is a horizontal section showing in detail the stop-collar andcooperating parts.

Theillustrated embodiment of the invention is shown in the, drawings asattached to the well-known Campbell wax-thread sewin'g-machine, whichneed not be particularly described. The awl 1 presser-fcot 2, andwork-table 3 are all of familiar forms.

Fig. 3 is a- The work-guiding attachment comprises a vertical post 4,secured to the frame of the machine and provided with a vertical socketfor the reception of a round stem 5, which may be raised or lowered inthe post 4 or proper position maybe 'securedbya thumbscrew 6, which isthreaded into lugs 7 in the upper end of the post 4 and operates to drawpurpose. em 5 carries on its upper end a horizontal bar 8, upon which isslidingly mounted a block 9, which may be secured in adjusted positionon the bar 8 by a set-screw 10. The block 9 carries the workuidingdevices, which in the illustrated embodiment of the invention are twoedgegages, of which one (marked 11) is formed integral-with the block9', while the other, 12," is provided with an arm 13, pivoted upon theset-screw 10. The arm 13 is provided with a socket concentric with theset-screw, within which is located a compression-spring 14, and thelower face ofthe arm has a slight depres sionengaged when the gage is inworking position by the rounded upper end of a pin 15, fixed in theblock. 9. By this construction the edgeage 12 is held normally inWorking position, Imt may be easily swung away by the operator againstthe resistance. of the spring '14 and pm 15 .when it is necessary totemporarilydiscontinue its useas, for example, in performing certainoperations on harness where the .pi'e'ces being sewed are of irregularform.

The edge-gage 1 1 is provided foruse where it-is necessary to use anarrower gage than the gpgclZ. B adjustin the block 9 along the at 8 thefrom the needle may be varied so as to adjust the distance between theseam and the edge of the work. 'The edge-gage 11 is not pivotallymountedupon the block 9, like the edge-gage 12, but provision is madeforswing: ing the attachmentas a whole, with the exany other work-guidingdevice which may be en stituted therefor may be swung into and out ofworking position during the operation of the-machine. To this end thestem 5 is provided with a stop-collar 16 which is s lit and providedwith a screw 17, by whic itmay be clamped upon stem 5. This collardetermines the height of the stem 5 in the post 4, so that when thethumb-screw 6 is the lugs-to'gleitlher, the post being split for this est istance o either edge-gage turned therein and which when adjusted toception of the post 4, so that the gage 11 or provided with adownwardly-extendingstop vided loosened the stem 5 and parts carriedtherebymay be swung in the post without changin their vertical position.

11 order that the work-guiding device when swung back to workingposition may always swing to the same point without attention on thepartof the operator, the stop-collar 16-is 18, which engages acorresponding lug 19 on the post 4. By loosening the stop-collar 16 andturning it upon the stem 5 the parts may be adjusted so that they willstop at the proper position, and until this adjustment is changed theywill always return to the same point. The stem 5 and parts carriedthereby may also be entirely removed from the post 4 to substituteanother attachment, and when replaced will return to proper positionwithout readjustment.

The stem 5, bar 8, and 'sto -collar 16, form acarrier which may be usefor various workuiding devices, the adjustments pro 1n these parts beinguseful in connection with the various devices, and though the Inventionis described particularly as used in connectlon with edge-gages it willbe understood that except in so far as the claim is specifically limitedto such construction it is intended to cover the use of the form ofcarrier shown in connection with various work-guiding devices.

Having now described the invention, what is claimed is- A Work-guidingattachment for sewingmachines having, in combination with the base ofthe machine, an upwardly-extending support provided with a verticalsocket and means for clamping a stem therein, a stem removably journaled injthe support and carrying a work-guide, a collar fixed butvertically and rotatably adjustable on the stem and engaging the top ofthe support, and cooperating stops on the collar and the support forlimiting in one direction, the rotation of the stem in the socket,substantially as described. In testimony whereof I aflix my signature inpresence oftwo witnesses.

WILLIAM WILSON.
